Here in lies the truth.....
You cannot have enough level 25's to fight them.
If you beat 1 or 2 in the first stage but use up all you level 25's trying to kill the 3rd boss, you have to start over
. With no wins.
Then after hours of reading, mapping out teams, noting strategies you muster the strength to go on. You try again & beat the first stage, you go into in the Final Stage. If you do not finish any of the final stage & exhaust your list of pets, YOU HAVE TO START OVER AGAIN!
I have spent 4 days!! Went thru all my pets. In desperation today before the reset I played 7 hours straight working all strats & possible combinations while watching YouTube celestial fights videos and reading WoWhead.
I somehow got thru all of them, ALL OF THEM but ONE!!! Went thru all of my pets just one more time hoping, wishing, screaming! Could not accomplish it.
Went out thinking "Ok I got past the first stage maybe it will not make me do that over & I can start at Final Stage."
It erased everything as if I had done nothing the past 7 hours.
I give up.
I may save enough in game gold to possibly purchase those pets.
I am truly ready to throw in the towel
Unless you want to face the most demoralizing, infuriating, humiliating in-game event.... enter the Celestial Pet Battles at your own risk.....You have been warned.
